T0 all-whom t may' macero.'

Be it known that l', Eisenmann lWnNnL, a citizen of the United States and a resident of lievi' "i'orli, in the county and State of New York, have invented certain new and useful improvements in lrite/iisionflables7 of which the following is a speciiication.

This invention relates to improvements in extension tables and has as its special object to provide a. table l'iavingi` an unbrolien top securely engif il with its supporting fraaie., and a plu of plate leaves which may oe extended in the saine plane the g"lier or both ends thereof., whereby ty or available area-oit the table sreased..

r objeot is to provide n'ieans i leaves are normally contained ole top9 when not in use, and which may e ijusted at the ends in a convenient inannei.y with the expenditure ol a minimum oi' pliy l enen Another object is to prot .de means whereby the leaves when. in an extended position, are firmly he d and supported, the joints be tween the leaves and the table top being drawn tightly together, so as to present no crevice or space therebetween. p

These and other like objects of' a similar nature are attained by tile novel construetion and combination oli parte hereinafter described and shown in the accompanying drawings, forming a material. ijvert of this dislosnre and in whichwhereby below the Fi re l is a side elevational view showing a le made in accordance with the invention Fig. 2 is an end view thereof.

Fig. 9 is a transverse sectional view taken on line l) E) of 8, and

Fig. l() is an enlarged fragmentary seclional view showingl thi` arrangement of one o lYA the reardiiig detente used in construction.'

ln the drawings the table `is shown to be supported upon four legs' or columns 20, which ma); be any desired ornamental design whatever, connected near their lower ends by rigidly engaging brace elements 21. The upper ends of the legs are ixedly secured at the inner corners of an open rcetangular traine, comprised of side elements .'-l and 26, secured together by any of the usual devices employed for suoli purposes.

:lit the center of this frame, and upon the upper side thereof. is i'irinly secured a cross piece Q7, held by astenings 28, its ends ei:- tending beyond the sides 2l, to the full width of the table. llpon this cross piece 2i', is supported the vtable top 50, the saine being substantially integrally foi-ined, its sides and ends extending marginally beyond the supporting?,` fr ine. rlhe table top is secured at a central point by a screw 3l, pass ing through an opening formed in the center of the cross piece 2T. the screw being loosely' received therein, and acting as a.

guide' for 'positioning the cover plate, its upper screw threaded end pasing into the plate 3:2. fixed in the lower side oi' the table top.

Formed near the ends of the cross piece 27, are slots 22 through which pass screws Z-ll'tlireaded into the lower surface of the table top., the heads of the screws being engaged upon the outer surface of bent 'lat springs $55, which normally hold the table top in close engagement with the upper sur-- outer, the sainebeing of uniform-thicknessand Width and normally supported upon the upper edges of the frame sides 24.

Secured centrally upon the lower surface of the inner pair of leaves 38, are brackets il. held by screws 42, the inner extcndin elements 43, of the brackets havin fixe Y ins 44 upon which are journaled bel -crank evers, their longer ends 45, bein adapted to make Contact with the lower surface of the table top, near its outer end edges, while the other, right angled, downturned arms 46, of the bcll-crank levers are engaged by pivots 47, with links 48, which extend ont wardly beyond the table, below the leaves 38 and 4:0, being supported and guided in clips 49, secured to the lower sides of the youter leaves 40, the links terminating in projections adapted to be operated in the man-` ner of a handle, the same extending through open slots 52. formed in the center of the upper edges of the end frame elements 26.

Attached to the lower sides of the outer leaves 40, are the ends of horizontal support bars 56, the extremities of the bars having projections 57, used in the manner of lian dles in withdrawing the leaves, and have beveled outer surfaces 58. Recesses are formed in the upper surfaces of the bars vreceptive of the inner leaves 38,` the bars passing through rectangular openings 61 formed in the end frame elements 26 and extend, when the leaves are folded, nearly to the opposite end frame elements, as can best be seen in Fig. 8.

Similarly engaged with the inner leaves 38, are other bars 62, arranged closely adjaceiit to the bars 56, and operated longitudinally with them by reason of their beingr engaged between projections 63, at the foot or the inner ends of the bars 56, and olfset shoulders 64, formed near their outer, thickened ends, it being understood that these bars arearranged in pairs at bothA sides of the table; thus each pair of bars 56 and 62 move 1n unison as the leaves are extended.

All of these bars normally rest upon the bottoms of the recesses 6l, supporting the leaves upon which the cover plate 30 normally rests.

In operation, when it is desired to extend one of' the leaves it is accomplished by grasping the extending handles 57, withdrawing the saine, whereupon both of the leaves 38 and 40, are retracted or brought outwardly, this action causes the inclined edges 58 to ride upon the bottom of the recesses 61, slightly raisin the adjacent end of the table top 30, unti the leaf 40, has passed its edge.

The leaf 40 at that time is supported on the end of the bars 56, the inner portions of which contact with the cross piece 27, while the bottom of the bars rest in the recesses 61 thereby supporting the leaf in a firm and secure manner.

-sions` 671 cngagcable with which are spherical headed. sliding detent-s 68, set in openings appropriately formed in the end frame elei ment :26, and pressed normally upward by the coiled compression springs 69, so as to engage in the depressions and draw the leaf tightly against the edge of the table top, the vdetente being held against loss by extending pius 7U, operating in slots 71, formed in the frame clcnicnts upon their inner-iside, as can be best secu in Fig. 10.

Should it be required to extend the inner leafl 38. suflicicnt force is exerted to overcome the friction of the spring detents 68 and draw the leaves out. which operation raises the inner leaf 38 to the level of the leaf i0 and `table top 30, the leaves heilig 'supported respectively upon the ends of the bars 56 and 62.

From the foregoing it will be seen the joint between the leaves is held tihtly to When it is desired to replace the leaves,

it is accomplished by pulling upon the extending knobs 50 which, through the links 48, operates the bell-crank levers, so that the longer arms 45, contact with the lower side of the table top, raising the outer edge sufficient to allow the leaves to enter therebelow, whereupon the leaves may be pressed into their original position, the same action taking place whether one or both of the leaves are to be retracted.

lVhen only the outer of the lea-ves is extended tlie link 48 rests in the central cutout 78 of the inner leaf 38, which is also recessed, as at 79, to permit the bell-crank lever 45 to freely operate.

In order to prevent inadvertent. raising of the outer leaves 40, pins 80, are set in their outer edges, the same engaging in recess 81, appropriately formed in the end walls of the frame, when the leaf is in a .folded position, and similarl other pins 82 are secured to the support iiars 56, maintaining the leaves level when the outer leaves are extended, the pins freely passing through the slots when the leaves are moved into either extended or retracted position and preventing their being raised inadvertently.

From the foregoing it will be seen that a mouse may be extended or folded in an easy. and

vconvenient manner, when in a folded position presenting a neat and attractive appearance and when extending to be firmly su orted.

avin'g thus described my invention what I claim as new and desire to secure by Le ters Patent, is-'- i l `1. In an extension table, the combination with a frame and supports therefor, of a,

fixed cross-piece on said frame, a solid table 1. top inclinably mounted on said cross-piece,

a'k pair of bow springs resiliently clamping said top to said cross-piece, pairs of leaves normally inteiposed betweenV said top and` said frame, independent support bars for A each'of said leaves, said bars being arranged in interengaged pairs, each of the members of each pair being movable in a vertical plane independentlyvl of the other, bell-crank levers mounted on the inner of said leaves centrally of said frame adapted to raise the adjacentv edges of said table top, means for actuating said levers, means for retracting said leaves, and means formed with said bars and said frame for automatically raising said leaves level with said table top when in an extended position. Y 2. In an extension table, the combination with a frame and supports therefor, of a .fixed central cross-piece on said frame, a

solid table top niounted on said cross-piece, means permitting contraction or expansion of said top relative to said eross-pieee, means permitting said top to be tilted in either direction, pairs of leaves normally disposed between said top and said4 frame at each side ofsaid cross-piece, a pair of longitudinally extending bars rigidly secured to each of said leaves, said bars being normally contained within said frame, means for extending said leaves, means formed with said bars for raising said leaves level -Witli said top when extended, said bars passing through recesses formed in the end elements of said frame, detents in said frame engageable with said bars as the `outer leaves are withdrawn, other detents engageable with lname to this specification.
